I'm getting ready to upgrade to the IOS exporter, and while putting touch control in a little game of mine, I had the thought about how to do a completely touch based platformer. I know there's plenty of games with on-screen buttons, but I was wondering if there have been any IOS platform games made that don't use the simulated control pad method, and how well they worked.
I'm thinking something along the lines of touching the screen and testing the touch points position relative to the player; something like: touch to the left of the player, and the player moves to that point. Touch above the player, and the player jumps. touch an enemy and the player attacks in that direction.
Has this been done before / any thoughts?
